My little girl is 6 months old and for the past month or so she has been grabbing at her ears when she gets upset. At first we were sure it was due to teething since she was also drooling profoundly, but she still has no teeth in sight and the ear pulling has only intensified. Now I'm worried that it could be an ear infection instead. She just had her 6 month check up less than a week ago and the doctor didn't seem concerned when she checked her ears but I'm still a little worried. How can I tell the difference between teething and ear infections? Should I bring her back to the doctor or wait it out and see if a tooth comes?
